9360024 Drory This objective of this research is to develop a novel interlayer to allow diamond coatings of higher quality than has previously been achieved to be deposited on steel substrates. Steels present a particularly difficult material for depositing high quality diamond coatings onto because of chemical incompatibility and the large difference in thermal expansion coefficients. The emphasis in the proposed work is to use a metal interlayer between the diamond coating and the steel substrate to alleviate these difficulties. The mechanical properties of coated test specimens will be determined. Friction and wear testing will be performed along with measurement of the coating cracking stress, interface fracture toughness and substrate yield strength. ***

9360024 Drory本研究的目的是开发一种新型夹层，使金刚石涂层比以前沉积在钢基底上的质量更高。 由于化学不相容性和热膨胀系数的巨大差异，钢是一种特别难以沉积高质量金刚石涂层的材料。 在拟议的工作中的重点是使用金刚石涂层和钢基体之间的金属夹层，以减轻这些困难。 将测定涂层试样的机械性能。 将沿着进行摩擦和磨损试验，并测量涂层开裂应力、界面断裂韧性和基材屈服强度。 ***
